Description

The present invention relates to a device for separating particles in the circulation of a fluid with a double extraction effect, and in particular to a device intended to separate from a liquid contained in jioro particles by depositing therein, the present invention also encompasses thus, one method and device for purifying a fluid to be treated biologically using one such particulate separator.

various types of separators are known, which, for the most part, subject a vortex-type vortex fluid to a housing whose shape typically has a conical part in which the particles are entrained by the fluid in motion to the tip of the vortex. conical pillar, i. of the conical part at the base of the device to be subsequently assembled into a sludge chamber _β Patent ia France No A - 2 205 369 describes one such separator for which a moving fluid disposed along the periphery at the fortex, m _o's. vortex, is entrained in utaiter Nata pail / container /.

Because separating devices of this type provide separation, by centrifugation, of the heaviest particles, leading them to the vortex periphery, their extraction, i. their separation from the aqueous / liquid / medium is only partially realized, since the rotational movement of the fluid continues in the precipitation chamber, which is what

prevents them from easily settling at the bottom of the latter. Therefore, such devices are not actually efficient enough.

The present invention is intended to provide a particle separation device which allows the extraction of solids, which are moved to the periphery of the vortex fluid and subsequently to be precipitated in a precipitation chamber, whilst avoiding the mixing of the solids. the treated / treated liquid with the precipitated impurities representing the residues from the previous treatment of the liquid.

The present invention also provides an object for the creation of a separating device that allows it to be created in the center of a basic, descending, i. downward rotational motion, an additional, secondary upward rotational motion that provides a secondary centrifugal separation of the solids remaining as a slurry after the first separation, such a second. * separation is followed by an extraction provided by the main ie. the basic spinning jog.

The present invention also aims to provide a means of facilitating the formation of a secondary upward rotating / swirling motion.

The present invention thus relates to a device for separating particles contained in a processable fluid, comprising a cylindrical housing closed at its upper end, which is provided with means for injection / injection of the processable fluid, which are tangentially oriented with respect to the inner wall of the casing in such a way as to create a forcibly swirling downward flow, wherein said casing containing in the base a single annular channel is circumscribed n from the inner surface of the cylindrical body and a central deflector assembly, the conduit is designed to evacuate the particles contained in the fluid to be treated, for generiraie / e> Start giving a central aihrosbrazen upward flow of process fluid \ an outlet axial tube provided at the top of the housing to ensure evacuation of the column axially of the treated _h luid outside the casing * «* vet® concieved MENT characterized in that deflector unit is composed of a deflector, ie. a deflection plate comprising at least one central planar portion, said plate having means for adjusting its position in the longitudinal direction, allowing it to change and adjust the cross-sectional value of the passage of said annular channel, and having the outlet axial tube being extended to the base by a single adjusting element

the wound of the created flow, from top to bottom, goth a conical part extending to the base and extended by a cylindrical part whose outer diameter is smaller than the inside diameter of the cylindrical body in such a way as to create between them a flowing stream for flow regulation a ring cross-section.

In one embodiment, the quality of the main rotary efflux is improved by providing a annular space enclosed between the inner wall of the cylindrical housing and the outer wall of the flow control member by one width approximately equal to one third of the inner radius of cylindrical housing.

The applicant also noted that the stability of the leaks (streams) received was further improved when the cross sections of the passages in the injection / injection fluid of the fluid to be treated were the same as the said annular space.

In addition, the applicant has found that, contrary to the prior art separators, it would be possible to avoid circulation; fluid inside the precipitating chamber, using a deflector / deflection / plate with a diameter greater than the inside diameter of the cylindrical body, such deflection plate being located below the bottom end of the cylindrical body such that the vertical component of the moving fluid is diverted from the baffle (plate), and this impedes the complete circulation of the fluid inside the sedimentation chamber. ^{and on the} contrary, the particles, by virtue of their mass, are, in their turn, caught (over driven) towards the end by the centrifugal force so well that they enter the settling chamber to be deposited thereafter / to settle / .

composed of a tube whose axis is perpendicular to the direction of the cylindrical body forming, and which tube is fixed to the housing, for example by welding. In order to ensure that the trajectory of the fluid is substantially tangential, only half of that surface in the housing of the housing corresponding to the opening of the fluid injection pipe is drilled, and it must be known, that this is the half located between the longitudinal axis of symmetry of said pipe opening and the corresponding tangential wall of the housing.

In one embodiment of the invention, the deflector element is composed of a circular plate pierced with a series of grooves made to connect its lower surface to its upper surface, such as the directions of the axis of these grooves on the deflector plate, from the side of the exits of these channels are tangentially oriented, which means perpendicular to each radius extending from the center of the slab and ending in the center of the outlet, with these channels directed in their extension from the lower to the upper th surface, in the same sense as does nagnetatelniyaya / inzhektsionniya® / channel * so as to increase the swirl flow created, to form the second central swirl flow. On the other hand, the axes of these grooves form, with the upper surface of the deflector plate, an angle -slightly-wedge-preferably -0-30. The inlets of these ducts are connected via a sewer (duct system) to the supply of fluid under pressure, preferably with the same fluid as that to be treated (treatment). This embodiment allows to assist in the creation / initiation / central vortex / vortex / leakage, such as, for example, that the fluid to be treated has been injected under such a low pressure that this pressure would not be sufficient to was secured by that central vortex flow. This latter, once established, may, in some cases, remove the fluid supply to the deflector Plate, the co-off - te - ha & a - y is no longer necessary to maintain. the vortex.

In another embodiment of the invention, a flat bottom is extending on the upper surface of the detector plate, the flat bottom, the inner edges of which are preferably rounded in such a way as to be an extension of the shape of the edge. flange / w to the inner surface of the housing. Preferably, the flat bottom has a diameter at least equal to the inside diameter based on the flow control member.

It is also known that biological treatment of water can be accomplished by means of bio-amplification / multiplication / methods, which consist of enriching a contaminated environment with specific micro-organisms intended to destroy, i. . remove pollution.

• 3a To develop, it is known that such micro-organisms need to be fixed, for example, in supports, of the mineral type. With such supports, loaded with micro-organisms, the latter go to the bottom of the water reservoir to be treated, from which the micro-organisms, evolving into the porous spaces of the supporting organisms, progressively escape to destroy the pollution in the environment. .

However, on the one hand, such micro-organisms-is-are-etched / do not tolerate / 'usually light, and on the other hand, their efficiency in their action is reduced when they are required to operate in conditions of waters subjected to turbulent flows or forced circulation, for example by means of pumps. At present, such a biological treatment system, as a consequence, can be difficult to use to maintain in a non-contaminated state shallow pools of shallow depth, such as those, for example, such as public bodies of water.

The present invention is therefore intended to provide one method and one device to enable it to be put into operation, i. The use of the particulate separator according to the invention to provide biological purification of a liquid is to provide, in particular, the maintenance of the above-mentioned pools by enriching the contaminated medium with the aid of of micro-organisms (specific) fixed on supports.

Accordingly, the present invention also relates to a method of biological fluid purification, characterized in that it comprises a fluid contact tank for treatment, or a biological reactor containing micro-organisms, fixed vorms -carriers, by pouring / bubbling / this fluid from the contact tank and injecting fe under pressure into a particulate separator to separate in the latter particles and support the micro-organisms contained in echnostta by collecting them in a retention chamber, in reinjecting them in the contact tank and ex- trahira »» $ m @ net © / extraction / the treated and clarified liquid from the separator.

The present invention is also intended to provide a device designed to provide biological fluid purification in a manner that activates micro-organisms fixed on a support carrier, characterized in that it contains a contact tank or biological reactor containing said micro-organisms into which a sewage pipe is fed to supply a fluid to be treated and / or purified, these contact tanks containing one outlet sewer pipe and means for pumping pulse / injection / impulse proper, to the inside of a particulate separator, to a treatment fluid and / or to be purified which is withdrawn from the contact tank, such as the precipitating chamber of said particulate ejection device: contains means allowing Particles and carriers containing micro-organisms separated from the liquid during the operation of the separation device are sent to the contact tank.

Thus, in Figure 1, the particle separation device according to the invention comprises a housing 1 representing a cylindrical metal tube whose longitudinal axis Y-L is usually vertical, but which may also, if necessary, be inclined. with this housing 1 being open at its lower end and containing at its upper end an annular chain / board / 3. A flap 5 formed by a circular plate fixed to the flange 3, for example by means of one, is attached to the flange or flange 3. series of bolts / not shown in the drawing /, p by means of an intermediate sealing compound 7 _O The cover 5 is προ lowered by a coaxial tube 9 fixedly attached thereto, for example by means of a weld, with the base of this tube 9 ending with a single element representing the flow regulator 10, wherein the same is constructed of a conical bottom portion 11 for low compression extending to the base, i. e. the lower part, and which conical portion 11 extends into a cylindrical portion 13, with a diameter smaller than that of the inner wall of the housing 1, in such a way that a ring passage 14 is formed between them.

The upper part of the housing x is provided with one injection12 on / discharge / pipe 15, which is the fixation fixed on the housing 1 by welding, and whose inner passage 12 enters, ie, is connected to the interior of the housing 1. The axis X - X ? of this injection tube 15 is tangential to the inner surface of the housing 1 and transversely,

I relation longitudinal axis Y - Y of the same. Outside the leaf end, this injection / injection / pipe 15 has connecting means, such as threaded ones, that allow I. to be connected to a single fluid source for processing.

The sludge chamber 17, constructed by a hemispherical tank 19, is attached to the base of the housing 1 by means of a horizontal upper / ceiling / plate 18 of the hemispherical tank 19. The base of the sludge chamber 17 is placed thereon. inner surface, a cylindrical support 20 extending along the longitudinal axis YY ^, the lower end of which a cylindrical support 20 is extended, in order to ensure a good fixation of the latter on the settling chamber 17. The base 20 is drilled through it is made entirely of threaded n a through hole 21 which also passes through the base of the settling chamber 17. In this threaded hole 21 is inserted a screw 23 whose upper end is connected to a circular deflector / deflection / plate 25 located perpendicular to the longitudinal axis Y - H, and with a diameter close to the outer diameter of the housing 1 to such an extent that it is capable of completely closing its lower opening. The lower end of the screw 23 extends below the settling chamber 17 and contains a square control head 27 designed to rotate it, thus making it possible, by screwing the screw 23, to draw it or less in a longitudinal direction. which means in the direction of the Y - Y axis _; of the housing 1, the deflector plate 25 relative to the base of the housing 1 in such a way as to regulate the cross-section of the passage formed by the annular space 26 existing between the upper surface of the deflector plate 25 and the lower edge of the pivot pin 1. One counter nut 29 screwed on the screw 23 allows the deflector plate 25 to be fixed with respect to the settling chamber x7, and hence, with respect to the base of the housing 1, in a predetermined set position.

In fact, the deflector plate 25 may also have a comically shaped curb (side / 24 / figure 2) extending to the lower part and inclined with respect to the longitudinal axis Y - Y ^ by about 45 °, by * '. * in such a way as to improve the shape of said annular passage space 26 and facilitate the passage of particles extracted from the fluid to be treated. The bottom of the sludge chamber 17 is provided with a discharge means 21, designed to provide removal of sludge from impurities collected during the operation of the device, such emptying means being, for example, a simple screw eye / plug / .

The operation of the device according to the invention is of particular interest, especially because it is uncluttered

On the left, a single effect with double effect spinning is realized.

Thus, due to the tangential orientation of the injection / injection / pipe 15, the fluid penetrating into the housing 1 tolerates, in a known manner, a rotary movement which is channeled via the conical part 11 of the flow control element 10, then from the cylindrical part 13 this element 10 to form a forced viewer. movement ο®) ί, which bears a deflection-C | contact with the deflector plate 25, and then forms a rotating axially rotating axial Y column, directed counter-inwardly of the flowing ο® X rotationally descending © movement, and which, indicated by Y upward movement of the stream, enters the interior space 16 of the flow control element 10 to be exited from the device in front of the pipe 9. The solids contained in the injected fluid are separated from the latter by the force of centrifugal forces of the rtelivo movement, and as soon as they reach the wall to annular passage space 26, they are pulled out from the housing 4, and discharged into the retention chamber 17, where they are precipitated / accumulate /. It should be noted that this precipitation is possible due to the fact that the moving fluid in the housing x is not drawn into the sedimentation chamber 17, since there is no connection in the

vertical direction, between the housing 1 and said precipitator- on camera 17. It is therefore extant a separation of, trans-

15.

during the treatment / killing treatment / in the housing 1 and the sludge, which forms a precipitation chamber x7, which is extremely interesting and hygienically favorable.

Following the deflection of the moving fluid at contact and with the deflector plate 25, the rotating center column Y exerts on the fine particles, remaining + a kind of suspension in the liquid, a centrifugal action so well that they are sent to the outer column X, which thus retrieves them and entrains them in their own motion to eliminate them through the annular transition 26.

Thus, the device according to the present invention, thanks to this zoological centrifugal separation, has an extremely remarkable efficiency (remarkable cleaning effect).

To favors the deflection of the fluid on the basis of this device, and as shown in Figure 2, the upper surface de _h .l ekternata / diverting / plate 25 is recessed so that it is made a central dish or dish 35, the bottom of which 33 is flat and the inner side 37 is inclined from the bottom to the height and from the inside to the outside with respect to the longitudinal axis Y - Y. Preferably, the one (s) on the inner wall of the housing 1 offorces one round 4, wherein the carved tray is oriented to the interior of the housing 1, which tangentially collides with the inner edge 37 of the nozzle 35. the axis 24 of the deuctor plate is inclined about 45 ° with respect to the longitudinal axis Y - Y of the device and the space formed between the latter and the base of the housing 1, forming a passage 26 for annular outflow.

The fact that according to the invention that the cross section of the annular passage 26 can be adjusted suggests that the particles move to the settling chamber 17, and the possibility of changing the longitudinal positioning on the basis of the centrally rotated movement Y allows to extend the area of the use of a particulate separator according to the invention, and to use, for example, one such device with liquid and hourly particles _with very different physical properties. paratypes.

In striking cases, the device according to the invention could be adapted to the requirements of the user by simply adjusting the longitudinal positioning of its deflector plate 25 for the multiple operating conditions encountered to achieve the optimum result.

The device according to the invention also permits, during its start-up, a predetermined positioning of the detector plate 25, which is extremely favorable for the establishment of forced rotary motion, and then, after the latter is formed, to be realized a new positioning, more favorable to the conditions for the desired separation.

The various positioning of the deflector plate 25 can, quite naturally, be controlled by automated means

In particular, in order to favor the incorporation, formation of vortices and the establishment of a vortex axial upward movement of the treated fluid, more injection / injection / fluid tubes may be required to cause it to contract the tangential forces applied to the fluid being treated.

In the embodiment shown in FIGS. And 4, three injection tubes 15a, ± 5c and 15c, spaced at angular distances equal to ο ^x ~ ^x / by 120 each, are used, and chitc ccc ^ are tangentially arranged with respect to on the inner surface of the housing 1. Injection tubes 15a, 15b, and 15c are arranged in three cross sections, located one below the other, and in which they are bumped / penetrated / sequentially from top to bottom respectively by the pipes 15a, 15b and 15Co.

In one embodiment shown in Figure 4a, the housing l comprises an injection tube 15 for the treatment / treatment / fluid which is disposed in such a way that one of its generators is tangent to a cross section of. housing 1. The inner groove of this injection tube 15 is in communication with the interior of the housing 1 by means of an opening 12a which is punched into the wall of the housing 1.

Cacti is represented on φ-games 4a and 4b, only half of the housing surface facing the inner duct 12 is punctured. The tanner device allows the liquid jets to be privileged, which are tangents to the inner wall of the housing 1, thereby polishing it.

in the formation of forced vortex motion.

According to an interesting embodiment of the invention, the deflector plate 25 is drilled into a series of pressure-filled fluid passage openings which are tangentially oriented to the plate 25 in such a way as to create fluid jets to assist the formation of central ascending vortex movement U. Thus, in Figures 5 to 9, the deflector plate 25 is intersected by a series of multiple grooves 40, for example, number eight, extending from the periphery to the lower surface 42 of the deflector plate 25, where they form an inlet creates 45 to come out on the top surface 44 of the plate 25, with its outlets 46. The outlets 46 are distributed evenly on a central circle with the center 0 of the plate 25 'and a radius r in such a way that a central angle corresponding ₀ © I separating the two outlets 46 to be equal to 45 _a These channels 40 are oriented in such a way that their axis of symmetry Z -X *, offsets, as shown in Figure 7, an angle ** 'angle A with upper surface 44 of the deflector plate 25, ⁷ (preferably within 30 ° _o ) shown in Figure 5, the orthogonal projection a-a ¹ on one axis of symmetry ZZ * of one cannel 40, at the outlet of one aperture 46, passes through the middle D of one section BC, which cuts the centers B and C to two respectively following one after another outlet opening 46 / by connecting in the direction T of the ascending vortices Y /. In fact, the applicant has found that this orientation of the grooves 40 at the outlet of the slab 25 would | (allow an optimum entrainment of internal

However, in this embodiment, and In the foregoing, the channels 40 preferably have at the output a rectilinear portion 40, the projection -aa ^x on the axis of symmetry having the same geometric properties as described in the previous implementations.
